Job description

Infrastructure Architecture & Strategy (30%)

• Design and evolve scalable, highly available cloud infrastructure spanning multiple regions and cloud providers (AWS, Azure, GCP)
• Lead infrastructure‑as‑code (IaC) initiatives using CloudFormation, Terraform, and other tooling; establish patterns and standards for infrastructure management
• Architect and implement disaster recovery, business continuity, and infrastructure resilience strategies
• Drive cloud cost optimization initiatives, implementing governance, monitoring, and right‑sizing strategies to achieve operational efficiency
• Establish and maintain security baselines, compliance requirements (SOC 2, ISO 27001, etc.), and infrastructure hardening standards

CI/CD Platform & Automation (15%)

• Design and manage enterprise CI/CD pipelines using GitHub Actions, Jenkins, or equivalent platforms
• Build and maintain self‑service deployment platforms that enable developers to ship code with confidence
• Lead testing shift‑left initiatives, including static code analysis, security scanning, and automated deployment validation
• Establish release engineering practices, version control strategies, and deployment orchestration across environments

Observability, Monitoring & Incident Response (15%)

• Design comprehensive monitoring, logging, metrics, and tracing infrastructure using tools like Prometheus, Grafana, Elasticsearch, or equivalent
• Establish SLI/SLO frameworks and error budgeting practices; define meaningful alerting and on‑call procedures
• Lead incident response and post‑mortem processes; drive reliability improvements through systematic root cause analysis
• Implement security monitoring, threat detection, and DevSecOps practices integrated with CI/CD workflows

Container Orchestration & Kubernetes (10%)

• Architect, deploy, and manage Kubernetes clusters in production environments; optimize resource utilization and cost
• Design containerization strategies, container image management, and registry solutions
• Implement service mesh, networking policies, and security controls within container platforms
• Drive adoption of Helm, operators, tooling (ArgoCD, Flux) for declarative infrastructure management

Technical Leadership & Collaboration (20%)

• Mentor and guide junior and mid‑level DevOps engineers; establish technical standards, code reviews, and best practices
• Collaborate with software engineering, security, database, and network teams to align on infrastructure requirements
• Drive technical documentation, architecture decision records (ADRs), and knowledge sharing initiatives
• Participate in architectural reviews, capacity planning, and technology evaluation for infrastructure modernization
• Advocate for operational excellence, automation‑first mindset, and continuous improvement culture

Network & Security Infrastructure (10%)

• Design and implement cloud networking architecture including VPC, subnets, routing, and security group policies
• Manage firewalls, WAF, DDoS protection, VPN, and ingress/egress patterns
• Implement zero‑trust security principles, identity and access management (IAM), and secrets management solutions

Minimum Qualifications

• Bachelor's degree in Computer Science, Engineering, or related field (Master's degree preferred)
• 15+ years of overall experience in software engineering, systems engineering, or infrastructure operations
• 5‑10+ years of hands‑on DevOps, Site Reliability Engineering (SRE), or platform engineering experience
• Proven expertise with cloud platforms (AWS, Azure, GCP) in production environments at scale
• Proficiency with Infrastructure as Code tools (Terraform, CloudFormation, or equivalent)
• Deep experience with Kubernetes in production; strong understanding of container technologies (Docker, containerd)
• Expert‑level proficiency with Linux/Unix system administration, networking, and security fundamentals
• Strong scripting and programming skills in Python, Bash, Go, or similar languages
